VoxTalks Economics

It’s cultural meme that teenagers in New York and Seoul will have more in common with each other than with their parents. Has where we come from been downgraded as an influence on what we like, or is there still what Thierry Mayer of Sciences Po and CEPR calls “gravity in tastes”?  His research focuses on a very important aspect of this question: regional French food. Is there still a France of butter, and a France of olive oil? And, if there is, can we draw it on a map, or is this now a cultural and social divide, rather than a regional one?

We are up to our necks in advice about how to innovate in business, how to succeed as a founder, or how to spot a great startup. Blogs, YouTube channels and airport bookshops claim to reveal the secret. And yet, investors and incubators have a very patchy track record in picking winners.  What if there was a better way to spot entrepreneurs who are more likely to succeed? Konrad Stahl of University of Mannheim is one of a team of researchers who have found one indicator of success that dominates all the others. He tells Tim Phillips what it is, and why it matters.

Today generative AI makes it easy to create and distribute convincing fake news stories, pictures, even videos. We’ve all been hoodwinked – but does that undermine our trust and confidence in the mainstream media? Ruben Durante of National University of Singapore, IPF-ICREA and CEPR is one of the authors of new research that tests how AI-generated misinformation affects our desire for real news. He tells Tim Phillips the good news and bad news for the future of the media’s business model.

The annual meeting of the World Economic Forum, in Davos, attended by thousands of business and policy VIPs – is one of those events that pops up on the news every year, as we see photos of multinational CEOs shaking hands with world leaders and taking part in panel discussions on the future of the planet. But how valuable is it to the business people who pay hundreds of thousands of Swiss Francs to attend? Does Davos create business value, or might it be a high-profile way for them to ski and party – in the words of a new discussion paper published by CEPR, is it any more than “a boondoggle”? Andreas Fuchs of University of Goettingen is one of the researchers who asked this question. He reveals to Tim Phillips the size of the impact on stock prices and credit ratings.

The belief that women are in some way inferior to men has been around for centuries. And throughout that time, women have suffered the consequences. Economists have lately been trying to understand more about the origins of gender biased norms, to help create better policies to challenge them. Their work can build on insights from sociology, anthropology and gender studies, but also raises important questions about the roles of men and women in society. So what should policy attempt to change?  Siwan Anderson of Vancouver School of Economics and CEPR talks to Tim Phillips about what we know on these topics – and the most promising directions for future research.

On 4 August, Paul Atkins, the chair of the US Securities and Exchange Commission, launched “Project Crypto”. The SEC wants to make the US “the crypto capital of the world”. Crypto investors make a lot of noise, but who are they, and do they behave differently to other retail investors? A new CEPR discussion paper called “Do you even crypto, bro?” summarises what a representative sample of US citizens think about crypto investments and highlights the gap in attitudes to risk and investing between crypto holders and the rest of the population. Michael Weber of Purdue University is one of the authors, and he tells Tim Phillips about the beliefs, the politics and the attitude to investment gains that have typified the crypto market so far.

How do criminals choose the weapons they carry, the number of accomplices, the types of business they target? Economists have long argued that decisions to commit economic crimes are strategic, based on a calculation of risk and reward.  The Italian justice system changes the punishment for a crime depending on how it is committed, and so a new analysis of thieves and their crimes, based on data from Milan, tests whether this is really the case. Giovanni Mastrobuoni of the University of Turin, Collegio Carlo Alberto and CEPR is one of the authors of this research. He talks to Tim Phillips about the economics of crime, the problems of collecting data about illegal acts, and Turin’s most famous gold heist. 

Recorded live at the PSE-CEPR Policy Forum 2025.  The gender wage gap in advanced economies isn’t shrinking. What can firms do to eliminate the part of the wage gap that comes from discrimination? The OECD has analysed the data from countries with pay transparency legislation to discover how much of the gender pay gap arises from the different treatment of equally qualified men and women. Stéphane Carcillo tells Tim Phillips what the research had discovered, and what the policy options could be.

Recorded live at the PSE-CEPR Policy Forum 2025.  One of the mysteries for economists and policymakers has been the reluctance of men to take paternity leave, no matter how generous the terms offered to them. In her presentation, Marianne Bertrand of the University of Chicago Booth School mentioned some new research from Japan that is helping to shine a light on this topic, in an innovative and entertaining way. We wanted to know more, and so Tim Phillips asked her about why, when bosses and employees both think it’s good to take paternity leave, most don’t. and why an anime video might change this situation.  Watch the anime video we discuss: https://talknorm.al/paternity

From our series recorded live at the PSE-CEPR Policy Forum 2025. How much progress have we made in finding out the source of gender inequality at work? At the Forum, Barbara Petrongolo of the University of Oxford and CEPR gave the keynote lecture on “Questions and challenges for 21st century labour markets”. In conversations with Tim Phillips, she points out that there are still many unanswered questions about the unequal role of women in that labour market, and that recent research often raises as many questions as it answers. If we find those answers, she argues, we can make society not only a fairer place, but unlock economic growth and productivity.

Recorded live at the PSE-CEPR Policy Forum 2025.  This week, we interview three of the next generation of economists. At the forum, a group of young researchers were presenting their work in the main theatre and at poster sessions during the breaks. Tim Phillips took the opportunity to talk to some of them about their research.  Pelin Ozgul of the University of Maastricht has investigated whether AI can improve training for call centre agents. Nathan Vieira of Aix Marseille University has analysed the efficiency of short-time work interventions in Europe’s labour markets. And Deepakshi Singh of the University of Groningen researched female employment in India during droughts – is a rise in employment a story of economic empowerment, or something else?

Are global economic flows collapsing, or are they reorganising? That’s one of the intriguing questions asked by a new CEPR publication called The State of Globalisation. It brings together a series of essays on both the changes that are happening in the global economy, and the policies that can respond to these changes. So how should trade policy and industrial strategy adapt when globalization isn’t so much retreating as rerouting? Michele Ruta of the International Monetary Fund is one of the editors. He talks to Tim Phillips about the way that firms, policymakers and institutions need to adapt, and the problems of doing that when they face an uncertain future.  Download the book: https://cepr.org/publications/books-and-reports/state-globalisation

Recorded live at the PSE-CEPR Policy Forum 2025.  Now that many of us work part or all our week at home, does that mean we want to move to a different area, or a larger house? And what is the effect on housing for those who cannot work from home? Morgane Richard of Stanford has researched how Londoners sought out new homes post-Covid to match their flexible work arrangements. She tells Tim Phillips what her models tell us about the long-run impact of their new working lives on house prices and rents for everyone living in, and on the edge of, the city.

Recorded live at the PSE-CEPR Policy Forum 2025.  Go back six or seven years and working from home was an exception. Bosses discouraged it, contracts didn’t mention it, and we didn’t have the technology to do it.  Covid changed all that. But since then, how have work patterns changed? Should we believe the press reports that we’re all being summoned back to the office, or is remote work now part of our lives – and what does that mean for employers and employees? Steve Davis of the Hoover Institution and SIEPR has been measuring the evolution of flexible working since the pandemic. He spoke to Tim Phillips about the far-off times when little work was done at home, who is taking advantage of the change in the way we work, and who benefited most from the Great Resignation and the changes in hiring and outsourcing that followed it. 

If we focus on the cutting edge of AI implementation, we’re also focusing on a small set of technologically advanced countries. How will AI affect work in the rest of the world, what should those countries do to prepare, and how can they make best use of the technology? Giovanni Melina of the IMF is one of the authors of two papers that calculates both the exposure of jobs to AI around the world, and the readiness of those countries to meet the challenge of using AI effectively at work.  He talks to Tim Phillips about the extent of the exposure to AI in emerging markets and developing countries, whether those countries have the infrastructure to implement applications of the technology, and the policies that would be most effective to increase their preparedness. 

 In the second of special series recorded live at the PSE-CEPR Policy Forum 2025, we are asking, how good is AI at doing real-world job task? And how can we measure their capability without resorting to technical benchmarks that may not mean much in the workplace? Since we all became aware of large language models, LLMs scientists have been attempting to evaluate how good they are at performing expert tasks. The results of those tests can show us whether LLMs  can be useful complements to our work, or even replacements for us, as many fear. But setting or grading a test to decide whether an LLM can do a problem-solving job task, rather than solve an abstract problem, isn't easy to do.  Maria del Rio-Chanona, a computer scientist at UCL, tells Tim Phillips about her innovative work-in-progress, in which she asks an LLM to set a tricky workplace exam, then tells another LLM to take the test – which a third LLM evaluates.

Recorded live at the PSE-CEPR Policy Forum 2025.  This year the annual Paris School of Economics-PSE Policy Forum is organized around three themes: artificial intelligence and labour reallocation, working conditions and remote work, and inequality in the workplace. In short, what's work going to look like in the future?  Our series of podcasts, recorded live at the event, starts with David Autor’s work on the impact of AI on jobs. Rather than speculate about how soon AI will destroy work, David’s research focuses on which tasks AI will automate, and what that means in terms of the expertise needed to do these jobs in the future. He tells Tim Phillips that some jobs will become more expert and some less – but the employment effects of AI may be the opposite of what many people expect. 

The Bank for International Settlements Annual Economic Report has just dropped, and there’s a markedly less positive tone than last year, when it was celebrating imminent soft landings in the global economy. It warns of a deteriorating outlook for growth, coupled with vulnerabilities in the global financial system.  So, what exactly is the BIS worried about, how can policy and regulation respond, and should central banks start worrying about the next systemic crisis? Gaston Gelos and Frank Smets are Deputy Heads of the Monetary and Economic Department at the BIS and are also two of the authors who put together the report. They talk to Tim Phillips about why last year’s optimism has disappeared, and how monetary and fiscal policy can adjust to cope with a new era of uncertainty and fragmentation. 

Whether you are looking at the link from education to economic growth, household earnings or individual happiness, there’s no doubt that a better-educated population is good news. But how can policy improve education in a cost-effective way? You might assume that a good route would be to improve the management of schools, but existing research is not conclusive, and often top-down attempts to improve management meets opposition from administrators. An experiment in Brazil has evaluated a program to improve management using existing resources in Rio de Janeiro. Tiago Cavalcanti, of University of Cambridge, Sao Paulo School of Economics & CEPR, and Felipe Puccioni of the Court of Accounts of Rio de Janeiro came up with the experiment, and they tell Tim Phillips about why universal education doesn’t necessarily mean universal learning – and how they became celebrities on national television when their successful project hit the headlines.

Pedestrianised areas, car-free streets, or low traffic neighbourhoods are increasingly visible in major cities. Whether in London, Paris, New York or Barcelona, these changes are always controversial – but does the loud criticism that we often hear in social media or newspapers really represent the views of voters who are affected by these policies? Elisabet Viladecans-Marsal of the Universitat de Barcelona, Barcelona Institute of Economics and CEPR spoke to Tim Phillips about whether Barcelona’s car-free “Superblocks” were vote-winners or vote-losers for the city’s mayor.
